I saw a few Tonnika sister kits and I really don't have the time or the skill to assemble and paint figures myself. The ~$40 a figure range isn't that bad for a finished figure considering the current price point of loose vintage figures and Hasbro figures are over $10 a figure.
For SS, I think he doesn't want to have too many projects going on at the same time. He certainly doesn't want to get caught up in the SLC craziness. I really wish I had found SS first before SLC.
Looking through SLC offerings, he essentially has only released SS product for the most part:
Bantha (no need to discuss this one)
2019 products - Han and Luke Stormtrooper, Yakface, Blue Snaggletooth, R2-D2 (pop up saber, Droids, Uzay), Stormtrooper, R2-Q5, Shadow Trooper, Yak Face
2020 products - ANH Luke Trooper, Stormtrooper (ESB, Droids, Glasslite, Uzay, POTF)
2021 products - Boba Fett and EV-9D9
2022 products - Rebel Trooper and Sandtrooper packs, Slave Leia, Thrawn, Droids and Uzay Boba Fett, Fett Throne
Planned Wave of 13 unreleased - Owen, Beru, Biggs, Wedge, R4-M9, Motti, Holo Leia, Captain Antilles, Spaceman (other four are Sandtrooper, Rebel Trooper, ST Han, and Thrawn - first two released in 4 packs only, last two made it to some customers)
Now that SS is doing the R4 figure, there isn't much that SLC has that are unique to them. Really just Thrawn, Fett Throne (if it even shipped), and Uzay Fett. This would lead me to believe most of SLC product was started or branched off of work by SS before he sold it to Krahn. I would say that leads more to the theory that Krahn was just a thief the whole time.
These are the SLC products I actually received: ST Han, Thrawn, Slave Leia, R2-Q5, Fett 3 Pack (Tri Logo, Uzay, Droids), Shadow Trooper
I would definitely say that SS's Fetts are better. ST Han is a bit disappointing because the helmet is hard plastic and doesn't have the feel of say the vintage Boushh or Skiff Lando helmets. Never had a vintage ST Luke, so can compare to that. Haven't got the SS Slave Leia yet, but everything I hear is that it is the superior version. R2 and Shadow aren't bad. Don't have the SS R2-Q5, but I think his astros are better overall from the ones that I have.
